WATCH K EY.

SPECIFICATION forming part of Letters Patent No. 231,173, dated August 1'7, 1880.

' Application filed June 21, 1880. (No model.)

To all whom it mwy concern:

Be it known that I, FRANK B. KENDRIOK, a citizen of the United States,residing at Lebanon, in the county of Grafton and State of New Hampshire, have invented a new and useful Improvement in Watch-Keys, of which the following'is a specification, reference being had to the accompanying drawings, which are a part of this specification.

My invention has reference to that class of watch-keys which are made to be worn suspended by a ring attached to the end of the key opposite to the winding-pipe, and is intended to provide a secure and durable swivel attachment, which will always revolve freely, never become clogged by accumulation of dirt, and will at the same time present a neat and attractive appearance to the eye.

In the drawings, Figure 1 is a side view of the finished key; Fig. 2, a longitudinal section of the same view; Fig. 3, a longitudinal section of the same view with the windingpipe, swivel-stem, and ring omitted; Fig. 4, an end view of the key; Fig. 5, the swivel-stem and ring; Fig. 6, the winding-pipe, showing dust-proof slot.

Similar letters refer to similar parts throughout the several figures.

A represents the body or handle of the key, which is made preferably from solid wire, plain, milled, or corrugated,-as may be desired, bored out from the end in which the pipe is to be inserted nearly to the opposite end, as shown at a in Fig. 3 of the drawings, but leaving a solid end, E, through which has been drilled a smaller hole at I) in said figure.

The end or head E may be of the same size of the body A; or, for the purposes of ornamentation, may be smaller or larger than the body A.

0 represents a stem made from solid wire, which may be of such size as to slip easily into the bore a, filling the same, but preferably of a diameter half way between that of the bore a and the hole I), said wire having been turned down, as shown by c in Fig. 5, to the size of the hole I), through which it is to pass easily, but with a square head, d, left on it, on which the body A is to hang, and having the hole 6 drilled through it horizontally near its small end to receive the ring D.

B represents the winding-pipe-of the key, which may be made solid, or with dust-proof slot.

When the parts have been formed the swivelstem 0 is dropped into the bore a, and remains suspended by the head (I, the small part 0 extending through the end or head E and projecting therefrom; the ring D is inserted in the hole 6, keeping the stem in place; the pipe Bis driven into the bore a as far as its shoulder f, and the completed key is thus formed.

It is obvious that a similar result could be accomplished byusing a tube for the body of the key and inserting therein the head or end E, or by boring out the end of a solid piece of wire and inserting a head through which the stem had been put; but I prefer to use the solid wire treated as hereinbefore described.

1 am aware that other devices have been used and patented to accomplish the same object; but they are all open to some objection whichin my invention I haveintended to avoid.

It is of the greatest importance that the attachment should be strong and durable, and also that the body of the key should revolve freely without turning the ring; otherwise the watch-chain, from which the key is suspended, will be wound up in the process of winding the Watch, causing great inconvenience. Some of the attachments now used are frail; some from their construction do not readily revolve or may become clogged with dirt, and all of them, so far as I know, are open to one or the other of these objections.

In my invention such strength is obtained that the attachment will last as long as the key.

As the only friction in revolving will arise from the contact of the head of the stem with the inner side of the head of the key-body, the body will always revolve freely, and as I make the small part of the stem long enough to permit of a little play in and out, it is readily freed from dirt.

I do not claim, broadly, a combination of a swivel attachment with the body of a Watchkey; but

What I do claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, in a watch-key, of the swivel-stem O, with head at and hole 6, and the ring D, substantially as set forth.

2. The combination, in a watch-key, of tho I body or handle A,hcad E, swivel-stem C,with 10 body or handlo A,h0a(l l:,S\\iVQl StClIl(1,itll head (I and hole 0, ring D, and windingpipe head d and hole 0,21Ildlillg1) substantially as i, with (lust-proof slot g, substantially as set shown and described. forth.
